(Cl. U-20V 1 Claim.

The present invention relates to new and useful improvements in haybalers and has for its primary object to provide, in a manner ashereinafter set forth, a machine of this character comprising novelmeans for placing the Wires around the bales as they leave the chamber,

Other objects of the invention are to provide a hay baler of thecharacter described which will be comparatively simple in construction,strong, durable, highly eicient and reliable in use, compact, and whichmay be manufactured at low cost.

All of the foregoing and still further objects and advantages of theinvention will become apparent from a study of the followingspecification, taken in connection with the accompanying drawingswherein like characters of reference designate corresponding partsthroughout the several views, and wherein:

Figure 1 is a view in side elevation of the chamber of a hay balerembodying the present invention.

Figure 2 is a View in horizontal section, taken substantially on theline 2-2 of Figure 1 but showing, a bale partially formed.

Figure 3 is a vieW in horizontal section substantially similar to Figure2 but showing the bale completed and ready to be tied.

Figure 4 is a cross-sectional View, taken substantially on the line 4-4of Figure 1.

Figure 5 is a view!l in longitudinal section through one of the tubularneedles with a Wire engaged therein.

Figure 6 is a fragmentary View in side elevation, showing the means forreleasably securing the tubular needles, one of said needles being shownin cross-section.

Figure 7 is a perspective View of one of the needles.

Referring now to the drawings in detail, it will be Vseen that theembodiment of the invention which has been illustrated comprises achamber I for the reception of the hay, said chamber.

1 which are adapted to be inserted transverselyV through the extension 4adjacent the chamber I. The needles l are provided with closed, pointedforward ends 8. The other ends of the needles 'I are open for theinsertion of one end portion of the baling wires 9. This is shown toadvantage in Figure 5 of the drawings.

The needles l are adapted to travel on rails I which are mounted on theouter faces of the side walls 5 through the medium of supportingbrackets II. The rails It) are in the form of metallic rods. Asillustrated to advantage in Figure 6 of the drawings, resilient latchesI2 are also provided on the side walls 5 for releasably securing theneedles 1 in the rear end portions of the slots 6.

It is thought that the operation of the baler will be readily apparentfrom a consideration of the foregoing. Briefly, the needles "i, with oneend portion of the Wires 9 therein, are positioned transversely in therear or inner end portions of the slots 8 where they are releasablysecured by the latches I2, said needles resting on the rails I0. As thebale, as at I3, emerges from the chamber I the needles l are pushedthereby past the resilient latches I2 on the rails I0, said needlestravelling in the slots 6. These needles are then withdrawn, leaving oneend portion of the wires 9 extending transversely across the extension 4at the front end of the bale being formed. These, or additionalneedles,`with the other end portions of the wires 9 therein, are theninserted in the rear end portions of the slots 6 and engaged behind theresilient latches I2. This is done while the plunger 3 is retracted. Thelast placed needles are then pulled on through the extension 4, leavingthe'other end portionsl of the wire extending through the hay at therear end of the bale. The end portions of the wires Vare then tiedtogether in the usual manner and the operation is complete.

It is believed that the many advantages of a hay baler comprising thepresent invention will be readily understood and although a preferredembodiment of the device is as illustrated and described, it is to beunderstood that changes in the details of construction and in thecombination and arrangement of parts may be resorted to .which will fallwithin the scope of the invention as claimed.

What is claimed is: f

A hay baler comprising a chamber including an extension, said extensioncomprising opposed side walls having slots extending longitudinallythereinto from one end thereof, brackets mounted on the side walls,rails mounted on said brackets and paralleling the slots, tubularneedles, for the reception of baling wires, engageable transversely inthe slots and operable on the rails, said needles being open at theirrear ends and terminating in closed, pointed forward ends, and resilientlatches on the side Walls for releasably securing the needles in theclosed end portions of the slots.
